今天看到for循环的操作，书中的操作例子如下：

>>>magicians = ['alice','david','carolina']
>>>for magician in magicians:
>>>print(magician)
alice
david
carolina

然后我照书操作，却出现下面的错误：
>>> magicians = ['alice','never','david','carolina']
>>> for magicians in magicians:
...
  File "<stdin>", line 2

    ^
IndentationError: expected an indented block

下面是书中的例子截图：

>>> magicians = ['alice','never','david','carolina']
>>> for magician in magicians:
...
  File "<stdin>", line 2

    ^
IndentationError: expected an indented block

我修改了，还是有错误

我刚刚尝试再次缩进，结果如下：

>>> magicians = ['alice','never','david','carolina']
>>> for magician in magicians:
...  print(magicians)
...  print(magician)
...  alice
...  never

谢谢啦

又有新的问题了，我加入其他指令后，显示语法无效，如下：

>>> magicians = ['alice','never','david','carolina']
>>> for magician in magicians:
...  print(magician.title()+",that was a great trick!")
...  Alice, that was a great trick!
  File "<stdin>", line 3
    Alice, that was a great trick!
                ^
SyntaxError: invalid syntax

然后我就一行一行打，到了was,又再次出现SyntaxError: invalid syntax，如下：

>>> magicians = ['alice','never','david','carolina']
>>> for magician in magicians:
...  print(magician.title()+",that was a great trick!")
...  Alice
...  Alice, that
...  Alice, that was
  File "<stdin>", line 5
    Alice, that was
                ^
SyntaxError: invalid syntax
脑壳疼啊，求解

我发现问题了，就是缩进那里少了一行，我真是死脑筋啊，还是谢谢指点
